ADJ USTABLE-FACED PLANE.

SPECIFICATION forming part of Letters Patent No. 318,331, dated May 19,1885.

Application filed February 6,1855. (Xe model.)

To all whom, it may concern.-

Be it known that I, EDWIN WALKER, a citizen of the United States,residing at Erie, in the county of Erie and State of Pennsylvania, haveinvented certain new and useful Improvements in Adjustable-Faced Planes;and I do hereby'declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to theletters of reference markedthereon, forming part of this specification.

My invention relates to improvements in plane-stocks and mechanismconnected therewith; and it consists of the improvements hereinafter setforth andexplained.

Figure 1 is a perspective View of my improved plane. Fig. 2 is aperspective view of my improved plane-stock frame with the adj ustableplates and other mechanism thereof removed therefrom. Fig. 3 is a sideelevation of the back half of my improved plane-stock with a portion ofthe adjustable plates removed, so as to show the bit-adj nstingmechanism. Fig. a is a perspective view of one ofthe central adjustableplates, showing a groove therein for the bit-adjusting mechanism. Fig. 5shows a front end view of my improved plane with a gage attached thereonfor adjusting the depth of cut, and also showing the plane adjusted toasquare-faced bit. Figs. 6, 7, 8, 9,10, and 11 are front end views of myimproved planestock, showing some of the forms to which the face of theplane-stock may be adjusted, (other portions of the mechanisms of theplane not being shown.) Fig. 12 is aside elevation showing a modifiedform of mechanism for securing the adjustable plates in place. Fig. 13is a perspective view of the under side of a doubleended matching-bit,showing the holes for attaching the adj usting-rod thereto. Figs. 14 and15 illustrate by perspective views some of the forms of bits to whichthe face of the planestock is adapted to be adjusted.

Like letters refer to like parts in all the figlllES.

In the construction of my improved plane, A is the frame, provided withthe guides D D D D, adapted to receive and support vertically-adjustablelongitudinal plates B B, &c.,

preferably of a different pattern.

which plates B B, &c., together with the frame A, make up theplane-stock.

The guides D D D are provided with slots D D D, in whichclamps G G Ooperate, these clamps O C 0 being secured by thumb-screws G GG',operating against the back side of the frame A. The frame A is alsoprovided with cars l? 1", between which the nut I of the bitadjustingmechanism operates. The front guide D of the frame may also be providedwith screws (1. a, &c., oncfor each of the plates B B, &c.

The frame A is preferably made of cast metal, except the handle F, whichmay be of wood.

The plates B B, &c., may be made either of cast metal or stamped out ofsheet metal, and any number of the adjustable plates B may be used,according to the thickness which it is desired to make the plane-stock.The two outside plates B B, fee, may also be provided at their frontends with small adjustable cutters b I), inserted therein for cuttingacross the wood when the plane is used as a dado-plane, and for otherpurposes requiring such cutters.

The frame A is also provided with holesin the back side thereof,(notshowm) into which guide-rods J J can be inserted when it is de siredto support a fence thereon. This fence K is connected to the slottedarms J J, which are attached to the sleeves J" J", which slide over therods J J and are secured in place thereon by set-screws J J", the fenceK being adjustable up and down 011 the slotted arms J J by means ofbolts passing through the slotsjj therein.

The bit H, I construct double-ended, so that either end may be used,according to the pattern desired, each end of the bit being made The bitis secured in place by means of the clip G and set-screw G therein,theclip G operating between the face of the bit and the lug E on theframe A.

For adjusting the bit H up and down, Iprovide an adjusting-rod, Lwhichhas lugs t i on the lower end thereof adapted to fit into holes h h inthe under face of the bit H, as shown in Figs. 3 and 13. This adjusting-rod I extends upward through grooves L in two of the central ofthe plates B B, &c. (Shown in Figs. 3 and 4.) Abovethe upper edges ofthe cut made by the planein dado-work and other work of that character.This gage M is also so arranged that itmay be detached and taken off ofthe plane-stock when desired and not needed for use thereon.

The front end views 5, (i, T, S, 9, 10, and 11 illustrate some of theforms to which the face of my improved plane-stock can be adjusted, bitsbeing used corresponding with such adjustment, (the clamping mechanismwhich holds the plates to the frame A not being shown therein.)

In operating my improved plane the plates BB, &c., are each adjusted inthe position dc sired and temporarily secured by the use oft heset-screws a a, &c., in the'front guide D of the plane-stock. Thesescrews a a, &c.. however, may be dispensed with, if desired, as theymerely form a convenient means of securing each plate in place duringthe adjustment of the face of the plane-stock to any desired form of bitprior to the plates being finally secured (after adjustment) by theclamps G C 0.

Any number of plates may be used in my improved plane, thereby makingany width of face on the plane-stock desired.

I am aware that planestoeks have been 1101 6- tofore constructedofadjustable blocks, so con structed and arranged with relation to eachother that the face of the plane-stock could be longitudinally adjustedto fit a circular surfaeefor example, the arc of a circle; but thisconstruction is not capable of any lateral adjustment of the face of theplane-stock to suit different patterns of bit. I am also aware thatplane-stocks have been constructed with detachable faces of differentpatterns, each pattern being suited to a particular form of bit made tomatch the pattern of the detachable face; but I am not aware of anyconstruction of a planestock prior to my invention con sisting of aframe supporting a series of thin longitudinal vertical plates, thelower edges of which plates combined formed the face of the planestock,and which plates were adapted to be vertically adjusted upon thesupportingframe, so that by such adjustment the face of the plane-stockcould be altered laterally'to adapt it to the use of any pattern of bitwhich the operator might have occasion to use in his work therewith.Therefore.

\Vhat I claim as new, and desire to secure by Letters Patent of theUnited States, is-

1. The combination, in a plane-stock, of a plane-stock frame with seriesof two or more vertical longitudinal plates which may be adj usted upand down -upon said frame and clamped thereto, substantially as and forthe purpose set forth.

2. In a plane-stock, the combination of a plane-stock frame providedwith guides and clamping mechanism with a series of two or more verticallongitudinal plates the lower edges of which form the face of theplanestock, said plates being vertically adjustable in said guides onthe plane-stock frame, substantially as and for the purpose set forth.

3. The combination, in a plane-stock, of a plane-stock frame and aseries of two or more vertical longitudinal plates which may be adjusted upon and clamped to said frame, with removable fence-supportingrods and a fence adapted to be adjusted both vertically and laterallythereon, substantially as and for the purpose set forth.

4. In an adjustable-faced plane-stock, the combination of theplane-stock frame A, pro vided with the slotted lugs l? I thereon, withthe screw-threaded adj usting-rod I, the thumb nut 1, operating betweenthe lugs I I, and the bit II, all operating together substantially asand for the purpose set forth.

5. In a plane-stock, the combination, with the plane-stock frame A andthe verticallyadjustable longitudinal plates B B, of the set-screws a a,substantially as and for the purpose set forth.

6. In combination with a plane-stock consisting of the plane-stoek frameA and the vertically-adjustable longitudinal plates B B. the adjustabledepth-gage M, substantially as and for the purpose set forth.

7. In combination with a plane-stock con sisting of a plane-stock frame,A, and vertically-adjustable longitudinal plates B B, clamped thereto,adjustable cutters b 11, substantially as and for the purpose set forth.

8. The combination, in a planestock, of a plane-stock frame, A, providedwith guides D D D, clamps O O O, the vertically-adjustable longitudinalplates B B, the bit-securing mechanism E G G, bit-adjusting mechanism II, and bit II, all constructed and operating together substantially asand for the purposes set forth.

In testimony whereof I affix my signature in presence of two witnesses.

EDWIN WALKER.
